Specification of Letters Patent.

Application filed May 15, 1914. Serial No. 838,830.

To all whom may concern:

Be it known that 1, CHARLES N. MINER, a citizen of the United States, residing at Albion, in the county of Orleans and State of New York, have invented certain new and useful Improvements in Jeweling-Tools, of which the following is a specification.

The object of ny invention is to provide a tool which may be used by watchmaiters for producing tae countersink or setting for jewels in watches with precision and expedition and in other connections where it is desired to cut an opening with great exactness as to dimension.

A further object is to so construct the tool that a measurement of the part to be fitted into the opening can be taken and the opening when out will be exact to this dimension.

A still further object is to so construct the tool that it may be adapted to be a part of the tail-stock of a lathe and the part to be operated upon can thus be held by the chuck of the lathe and revolved adjacent the tool.

\Vith other objects in view, which will be referred to, my invention consists in the peculiar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings :-Figure 1 is a view in side elevation of the tail-stock of a lathe showing my invention applied thereto. Fig. Qis a top plan view of the disclosure in Fig. 1. Fig. 3 is a transverse sectional view through the pedestal of the tail-stock on the line 3-3 of Fig. 1. Fig. i is an end view of the tail-stock showing the inner end. Fig. 5 is a view from the outer end of the tail-stock. Fig. 6 is a view in side elevation of the upper part of the tail-stock taken from the opposite side to the disclosure in Fig. 1. Fig. 7 is a view similar to Fig. 1 with the upper part of the tailstock in longitudinal vertical section more clearly to illustrate the structure. Fig. 8 is a transverse vertical sectional view on the line S-8 of Fig. 2. Fig. 9 is a similar view on the line 99 of Fig. 2. Fig. 10 is a fragmentary sectional view on the line 1G10 of Fig. 2. Fig. 11 is a view in side elevation of a burnishing point which may be inserted in the tool in the place of the cutting blade and used to secure a jewel in the settlng formed by the tool. The tail-stock 1 is to all intents and purposes of the standard design, it having the tail-stock spindle mounted in a bearing 3 on the upper end thereof to have endwisc sliding movement, and a locking collar is received around the spindle 2 to be tightened thereagainst by the thumb nut 5 to hold this spindle against endwise movement. The clamp 6 is provided to secure the tail-stock adjustab'ly to the bed of the lathe and the clamp lever T is extended through the side of the pedestal to a position to be manually actuated to operate the clamp. A plate 8 has blocks 9 and 10 secured thereto and these blocks have openings therethrough in which the spindle 2 is loosely mounted, the block 10 being split at 11 adjacent the opening in which the spindle 2 is received and a clamp bolt 12 provided to draw this split portion down against the spindle and clamp the spindle end firmly within this block. A gage opening 13 is formed in the upper face of the block 9 to one side of the disposition of the spindle 2 and a gage member 1.4: is received through an opening formed in the block to project into the gage opening 13 and to be adjusted by adjusting nuts 15, the set screw 16 being provided to secure this gage to be stationary when it has beenbrought to the proper adjusted position. an orifice 17 is formed through the opposite side of the block to communicate with the gage opening 13 and a gage member 18 ismounted in this orifice to have endwise sliding movement and to be in alinement with the gage member 14:- A pin 19 is carried by the member 18 to extend downwardly and project through a slot formed through the plate 8, and at its lower end this pin 19 is bifurcated to receive the reduced end of a stock 20 slidably mounted in an orifice 22 provided to extend horizontally in a block 23 secured through the plate 8 immediately be low the disposition of the block 9. A coil spring 944: is received in the orifice 22 behind the stop 20 to normally force this stock to extend from the orifice and a set screw is provided on the block 23 to be set against the stock and hold this stock against endwise movement in the orifice 22.

The block 10 is cored out in its middle portion as at 26 and a slide bar 27is mounted in the block. to extend across this cored out portion and a coil spring 28 received around one end of the slide bar 27 holds this" bar noimally moved to one of its extreme positions. A block 29 is rigidly secured on the slide bar 27 to be preferably directly adjacent the end of the tail-stock spindle 2 and 7 this block is provided with a longitudinal tapered bore 30 in the same horizontal plane with the center of this spindle C to receive.

the shank of the lathe tail-stock center or in the present instance to receive the shank 31 of-the cutting tool A pin 33 is provided to pro ect'fi'om the lower side of the slide bar 27 and a rocking lever 81- pivoted to the plate 8 at 35 has the one end slotted at 36 to,

receive the pin 19 on the gage member-18 and the opposite end slotted at87 to receive the pin 33 on the slide bar 27. lnthe present' disclosure 1 have shown the cutting tool 32 formed to have the cutting edge 3-l, thereof in alinement with the center of the spin ed in a chuck, or if the'jewel is to bemounted in a plate, the plate is held in a universal head or face plate on the revolving head of the lathe in the usual manner with the point at which the jewel is to be set directly in line H with the tail center of the lathe. By exerting pressure'upon the slide bar 27 against the tension of the spring 28, the lever 31 is swung around its pivot 85r'and the gage member 18 is withdrawn fromsuch close proximity to the gage member 14, with the parts in this position, the jewel is placed within the opening 18 and the gage member 18 is permitted to close lightly upon this jewel due to the tension exerted against the slide bar by the spring 28, the stop 20 is at all times in engagement'with' the pin 19 due to the spring pressure exerted by the spring 24: and when the size of a jewel has been determined in the gage the set screw 25 is brought into engagement with this stop 20 tohold the part in the exact measure of the jewel. The piece in which the orifice for the reception of the jewel is to be formed is being revolved by the head of the lathe and by exerting pressure against the knob .39 on c the rear end of the tail-stock spindle 2 this spindle is moved through the bearing 3 and the plate v9 and parts carried thereby are also moved forward to a position that the cutting tool 32 isbrouglit into engagement withthe piece to be cut and the orifice is formed therein to-the exact dimension ofthe jewel as measured between the gage members 14: and 18, which measurement is preserved by the stop :20. After the orifice is cut, the tail-stock spindle I is moved rearjewel may be placed in secure the jewel in place andto accomplish this burnishing action, I provide a burnishing tool 40 which may be fitted in the socket 30 when the cutting tool 32 is removed subsequent to the cutting action; This burnishing tool 40 has the ,burnishing 'point 41 thereof offset slightly from thedisposition of the cutting edge38 of the tool'32 so that as the tail-stock spindle 2 isagain moved a through the bearing 3 by exerting pressure upon the knob end 39, this burnishing point 41 comes into contact plate around the jewel and presses the metal firmly against the edges of the jewel to hold it in place.

From the foregoing, it will be seenthat have provided a jeweling tool which can be constructed as a part of the tail-stock strucwith the'metalof the 7 ture of a watchmakers lathe and whiclr does not interfere with the normal use of the lathe, the socket 3O beingof a dimension to-receive the tail-stock center when the-machine'is' to be used as a lathe and the side swing of the block'29 permitting this tail stock center to. be shifted to the one side or the other to'cut a taper'cylinder, further it will be seen that while this tool has been described as a jeweling tool for the use of watchmakers and is perhaps particularly well adapted for use in setting balance hole jewels, cap jewels, or plate jewels in watches, that the structure is equally well adapted to use upon a lathe of any other type and that a measured opening can be cut to the exact dimension of the part as measured.
